Speoication of Letters Patent.

Patented Aug. 19,1913.

Application filed Hatch 14, 1812. Serial No. 683,309.

To all whom it ma concern le it known t iat l, FRANK H. CRUMP,

citizen of the United States, residing at Los y the necessity ofremovingthe covers of thel binder.

The invention contemplates-the provisiom.

a binderofv this classz'oclamping mem'- bers which are connectedby meansof posts comprising telescopic sections, one clamping members carryinymeans for ad justably clamping `one of 1e said post sections andhavingsecured thereto one .end of the other sections of each post.

held at relative adjustment within certain limits so as to permit of theinsertion offa number ot extra. building up the posts by the use ofaddi-l tional sections.

Jinother aim of the invention is to provide means so arranged upon theleaf-supporting to prevent the leaves or retaining posts as held by thebinder becoming relatively dis-l placed when the clamping members o thebinder are separated, for the insertion or removal o leaves.

A. further object of the invention is to provide within the posts, meansfor automatically extending the sections thereof when the binder isunlocked.

For a full understanding of the invention reference is to be had to thefollowing description and accompanying drawing, in which Figure 1 is aview partly. in elevation and 4partly in longitudinal sectionbf the.binder embodying the present invention, Fig. 2 is a detail verticalvtransverse sectional view through ajportionthereoj Fig.,` 3 is a deftail view partly in elevation andA partly in ot leavesv Bysuch aconstruction, the clamping members, may be leaves if desired without'section illustrating an element employed in buildingl up the posts ofthe binder.

Corresponding and like parts are referred to in the followingdescription and indicatedin all the views of the accompanying drawing bythe same reference characters.

In the drawing, the lower clamping member of the binder is indicated ingeneral by the numeral 1 and the upperclamping member is indicated bythe numeral 2. The lower clamping member includes a flat tubular bodymember 3 against the under side of which there is disposed a filler 4which may be secured directly to the body-member 3 or may be heldthereto by the usual binding (not shown) which covers the back-boards ofthe binder.

, The upper clamping member of the binder consists of a' iiat tubularbody 5 which corresponds to the member 3, and a filler 6 correspondingto the filler 4. The back-boards of thebinder, are secured to theclamping membersl 1 and 2 by meansof hinges, each consisting o fa air ofattaching plates 7 secured between t each clamping member and supportinga hinge-rod 8 upon which are carried a number of leaves 9 secured in anysuitable manner to the'respectivebaclrboard For apur- Yose to bepresently explained, the upper and lower walls of the hollow body 3 othe clam in member l are formed with vertical y a ined openings 10 and11 and the filler 4 of this clamping member is vformed with an opening12 which registers with the opening 11.

A strip 13 is secured in a recess formed in the under side of the filler4 and closes the lower end of the opening 12 as shown in Figs. 1 and 2of the drawing. Also, :for a purpose to be presently explained, thewalls of the bod 5 of the clamping member 2 are formed with verticallyalined openings lll and the filler 6 is formed with an opening l5 and acountersink 16.

Each of the leaf-holding posts of the binder includes a section 17 whichhas its i lower end threaded into an opening in the strip 4 as at 18 andindented as at 19 so as to prevent its removal or accidentaldisengagement, and this section of the post is ormed or provided at itsup er end with a head 20. lach post also incibdes a section i 21 whichis interiorly reduced in diameter e tubular body and filler of I at itslowerend asat 22 and the lsections17. and 21 'are` assembled-with the.latter slidably receiving the former., Byiproviding the section 17with'the head :20 andini-` teriorly reducing the section 21 completeseparation of the sections isprevented. As'

creased in diameter as at 23 and interiorlyv decreased in diameter as at24, it being interiorly threaded to receive' a plug 25 which is irovidedwith a milled head 26, the perip iery of which projects beyond theexterior surface .of the section at its said end. The said up er end ofthe section fits slidably throup when the c ampinff members of thebinder are fully separated the head of the plug 25 as illustrated inFig. 1. By interiorlyv reducing the section 21 at its u er end ashoulder is formed against whidli bears the upper end of a spring 27housed Withinthe said section. The lower end of this spring bearsagainst the head 20 at the upper end of the section 17 and the springbeing'under compression it at all times tends to relatively separate orextend the sections1 17 and 21,3su'ch extension bein ,'hoyvever, nori.mallyprevented throught e mediumof a locking device' housed Withinth'e'ibody 3 of the clamp` g member 1 andl coperating with the section21 ofthe post. Theloekingdevice mentioned above consists of a,channelbar 28 which is slidably arrangedwithinl the bodyy 3 and yhas thelowery edges of its anges resting 'upon the bottomwall of the said bodymember 3 and its connecting portion 1 ing immediately beneatli the upperwall o the said body.r The said connecting portion of the channel bar isformed with openinvs 29 which register with the openings 10 when the baris in one position, but are arranged to be brought out of registrationwhen the bar is a justed longitudinally Within the said body. In one endof the bar 3 there is lixed'a plug 30 into which is adjustably threadeda stem 31 carrying a collar 32 which is rotatably conlined within thebody 3 but held against displacement longitudinally thereof. Beyond thecollar 33 the stem 31 is s uared as at 33 for the engagement-therewit ofa suitable key (not shown) by means of'v which the stem may be rotatedyso as to adjust the channel bar within lthe body. At this point it willbe readilyund'erstood that whenthe openings 29 are in registration with"the openings 10 .the lower endportion of the section' 21 of'eacli ofthel leaf-holding posts vmay begslidabl i adjust adjusted through thesaid openings and t rough the openings 11 and 12.' However, when theclamping members 1 and 2 are in closed relation, and the stem 31 has-been adjusted so as to longitudinally the channel bar 28 within thebody 3 and bring the openings 29 out of registration'with the openings10, the walls of said o enings 29 will bind the sections 21 against t iewalls of the openinos 10 and the sections of the posts will be heldagainst relative separation or extension, thereby holding the clampingmembers against separation.

From the foregoing it will be readily understood that the leaves of thebinder are to be fitted to the posts in the usual manner, and that theyare to be clamped between the members 1 and 2. It will also beunderstood that when it is desired to insert new l leaves or to removecertain leaves, the stem the openinvs 14 and 15 and 31 may be rotated soas to cause the o cnings 29 in the channel bar 28 to register with theopenings 10, thereby releasing tlie will be' received Within thevcountersink 16,

sections 21. The s rings 27 will then iin- ,mediately act to lift theclamping member 2 and permit of the insertion or removal of the leaves.it will furthermore be noted that the walls of the openings 29 engagewith the sections 21 `of the posts a considerable distance above thelower ends of these sections so that anumber of additional leaves may beinserted Without the necessity of increasing the length of each post.

As a means for preventing relative displacement of the leaves when theclampingr members 1 and 2 are separated, a sleeve 3e is loosely ftted'uon each post section 21 and these sleeves, eing of a diametersubstantially equal to the exterior diameter of said sections 21, and ofconsiderably greater diameter than the sections 17 hold the leavesagainst engagement with the said sections 17.

In Fig. 3 of the'drawing there is shown i oneof anumber of sectionswhich may be employed in building u the posts so as to increase theirlength an this section is indicated by the numeral 5 and is ofsubstantially the same diameter exteriorly as the enlarged upper end 23of the section 21. The section 35 is formedy at one end with a threadedstud 36 of a size to tit within the threaded upper end of the section 21after the plug 25 has been unscrewed therefrom and is formed in its oposite end with a threaded socket 37 whic may receive the stud 36 of thecompanion section 35, 0r may receive the headed stud 25.
